I'd make sure to provide beet pulp as part of his daily
ration at home as well. It takes time for the gut to adapt to new
feeds, or increased amounts of a feed. My husband's Paso Fino, which
he rides in LDs, is particularly sensitive to increases in amounts of beet
pulp...if we increase it too quickly, he'll develop a painful gas
colic. So, we feed beet pulp every day, and several days before a
ride, we'll begin gradually increasing the amount he gets to what he'll be
getting at camp.
